If I go to the mountain to collect medicine, how can the collected medicine become ointment?

There are many ways to turn plants into paste, but the problem is that they can't treat diseases. Maybe many people, including ordinary people, Chinese medicine and western medicine, will attribute the recovery of some used Chinese medicine to the credit of the drugs used. This is the so-called intuitive curative effect, but it is not the effect of drugs.

Many people don't know what can prove the effectiveness of drugs, and think that the intuitive curative effect can prove that drugs that have been used for hundreds of years will be effective, which belongs to the curative effect of reasoning. None of these can prove that the drug is effective. The only thing that can prove that the drug is effective is the conclusion of a large sample of randomized double-blind controlled clinical trial data.

If intuition, association and reasoning can prove that drugs are effective, then ancient witch doctors and any behavior, language and object can cure diseases.

Moreover, "herb picking" is a false concept, which can only be used to pick plants, minerals and other items. To make medicine, it must grow in nature to become medicine (the ancients thought it was medicine because they had a shallow understanding, that is, stupidity).
